17 Claims.

My invention relates to a coin selector and slug rejecter, and means toprevent fraud by using a slug in place of a coin to operate any machine.I have illustrated primarily the coin selector and slug rejecter withoutshowing its direct application to a coin operated machine. However, itwill be apparent from this and other descriptive matter herein, that mycoin selector and slug rejecter may be associated in any desirablemanner with such machines or devices where it is necessary to use a cointo operate the same. The slug rejecting mechanism of my device is of asimple character and is adapted to be operated to reject a slug andprevent it from being used to operate coin controlled devices.- Therejecting mechanism may operate to reject the slug before it enters thecoin controlled mechanism which operates the device.

.for preventing any kind of a slug from being used to operate a coincontrolled apparatus, whether it be a telephone or a machine where acoin slot is provided. Further, my selector and rejecter may beassociated with any coin operated mechanism for dispensing goods orarticles sold through a coin operated machine.

Heretofore, slugs of various characters have been used to operate coincontrolled devices, thereby fraudulently obtaining goods or servicethrough the use of such slugs. These slugs have been made to closelyimitate the coin of the denomination required and it has been almostimpossible to stop the use of the same. Some of these slugs are formedwith a hole therein, while others are of a disk-like nature, eitherhaving smooth faces orformed with printing or other fancifulconfigurations on the faces thereof.

These-last coins which have certain representations on the facesthereof, are made to simulate a coin or to indicate that the slug is ofa certain value in merchandise or the like, but all of these slugs aremade of the proper diameter to represent a particular coin of a certaindenomination,

so as to imitate the same as closely as possible. These slugs are oftenmade of approximately the same weight as the coin thatthey are designedto imitate, thus making it even more dimcult to detect them and causethe same tobe rejected before they manipulate the coin controlleddevice.

A feature of my invention resides in providing a coin selector and slugrejecter which is capable in the one device of detecting and rejecting aslug, whether it be smooth-faced or formed to imitate a coin,cr even ifthe slug is formed with a hole therein, and also to select the propercom A feature resides in providing a simple means in a manner to retainthe same while the slugs in virtually any form are rejected. Therefore,I have provided a means with a wide range of utility in accomplishingresults which I believe have not been possible heretofore in a singleunitary selector and rejecter. While devices have been made to preventthe use of slugs, they have failed in not having suflicient range toprevent the use of almost any type of slug. With such old devices, itwas only necessary for the operator to carry a variety of slugs and ifone would not work, another one would probably do so. With my device,the operator is not able to use these different slugs, for any slugswill be detected and rejected so they are worthless, and 15 theproprietor of a coin operated device is there- .by protected in the useof the same.

These features and other details will be more fully and clearly setforth throughout the specification and claims.

My coin selector and slug rejecter A is illustrated as a unitary devicecontained within a suitable casing which is provided with a top HI, endwalls II and side walls l2 and ii. The cover III is provided with a coinreceiving groove l4 formed in the coin tube l5.

The drawings illustrate the coin selector and slug rejecter Aas a unitof itself and not attached to a coin operated device, because it will beapparent that the same may be attached in any suitable manner to fitvarious different coin operated devices, so as to be of the proper sizeand dimensions to operate therewith. There are a large variety of thesedevices and owing to the fact that it would not be practical to showthem all, I have simply shown my coin selector and slug rejecter in itsvarious forms and in larger detail, so as to more clearly illustrate theoperation of the same and to'permit the parts to be more readilydescribed.- I have, however,- shown one application of my coin selectorand slug rejecter to an ordinary toll telephone box, as i1- lustrated inFigure 1'7.

The detector A is provided with an operating handle l5 which operatesthe trip I! to push the same forward into the dotted line positionillustrated in Figure 3 and when the operating lever l6 reaches thisinward position, the trip I1 is automatically released and permitted tobe forced back into its original position. The operating lever I 6 canbe then pulled out into position to be reoperated. As the rod I6 ispulled out, the shoulder l8 which operates the trip I! ratchets over thespring dog l9 of the trip H.

The trip lever i1 is mounted upon a transverse shaft 20 and is adaptedto operate the same each time the hand lever I6 is forced inward. Alever 2| is mounted on the shaft 20 and is formed with a curvedoperating end 22 which engages the end of the vacuum cylinder B. Aspring 23 holds the end 22 in engagement with the cylinder B. Thebackward movement of the lever 2| isladjusted by the set screw 24carried in the end The vacuum cylinder B is supported by the bracket 25which is secured to the bottom 26 by the screws 21. This frame is formedwith a vertically extending wall portion 28 upon which the of the lugl8. This operation is of primary importance in carrying out some of theprinciples of my selector. Within the vacuum cylinder B. I provide aplunger 32 which is slidably supported in the vacuum cylinder and isnormally caused to be held in projected position by the inner coilspring 33 which engages in one end of the cylinder 30 and against theshoulder ofthe collar 34 in the end of the plunger 32. This plunger 32is provided with a sharp working face 35 which is adapted to engageagainst the coin or slug in the operation of the selector A, asillustrated in Figure 7. In this figure, the coin 36 is in position tobe engaged by the sharp working edge 35 of the plunger of the vacuumcylinder B and the plunger is shown compressed within the vacuumcylinder while the vacuum 'cylinder is compressed within the baseportion 29. The parts as illustrated here in Figure 7, show the samejust prior to the moment of release of the lever l1 and before thevacuum cylinder B automatically is expanded by the spring 3|.

I have illustrated in Figure 9, a slug 3? which is formed with an outerannular bead around the faces thereof and a central opening 31'. InFigure 10, I have illustrated a slug 38 which is formed with smoothouter faces. In Figure 11,

I have illustrated a slug 39 which is formed with an annular head aroundthe same, similar to a coin and also formed with printed matter thereonto simulate a coin, as well as to be provided with a numeral indicatingthe denomination thereof, such as 5. These figures illustrate some ofthe slugs that are commonly used to fraudulently operate coin operateddevices.

The coin groove is formed to lead down to a position in axial alignmentwith the vacuum cylinder B. I provide a gate arm 40 which is pivotallysecured at 4| to the wall 28 of the bracket 25, as illustrated in Figure6. The arm 40 normally is held in the full line position illustrated sothat the arcuated edge 42 will form a shoulder against which the coin 36or any of the slugs 31, 38 or 39 will rest when they have been insertedinto the coin groove I4. The gate Ill remains in the full line positionuntil it is automatically tripped, whereupon it moves into the dottedline position. The tripping of the gate arm 40 takes place just prior tothe tripping of the vacuum cylinder B and after the working edge 35 hasengaged the coin or the slug.

The gate. is adapted to be tripped by the bell crank lever 43 which ispivotally secured at 43 to h a bracket supporting member extendingforward from the wall 28 of the support 25. This bell crank operates therod 44 in a manner to pull the gate into the dotted position illustratedin Figure 6. The bell crank lever is engaged on one end between theshoulders 45. The shoulders 45 are carried by the inner end of the rodwhich extends along below one side of the vacuum cylinder B. The innerend of the rod 46 is slidably supported to the under part of the base 29of the cylinder B, while the front end of the rod 46 is slidablysupported in the plate 4! which is mounted on the end of the cylinder B.The plate 41 engages with the coil spring 48 which in turn engagesthe'collar 49 on the rod 40, as the cylinder I B is compressed inward,causing the rod 35 to move the gate 40 into inoperative position afterthe working face 35 has engaged the coin or the slug. As the vacuum.cylinder B is released and caused to expand, the plate 41 engagesagainst a 7 enemas coil spring 50 which is supported on the outer end ofthe rod 45 and is held thereon by the shoulder collar adjustably securedto the end of the rod 46. Thus, as the cylinder B is exanded, theshoulders 45 will pull the bell crank 43 back into the positionillustrated in Figure 5, which will cause the rod 44 to push the gatearm 40 back into the full line position illustrated in Figure 6, forminga shoulder for a coin or a slug to hold the same in position to betested as to its character.

I provide a means of detecting and rejecting a slug with a hole in it,which includes a hollow plunger 52 which is slidably supported in the.

plunger 32 and the cylinder B, as well as being concentricallypositioned to the working edge 35 of the plunger 32.

A rod 55 is slidably positioned within the hollow plunger 52 and isformed with a pointed end 56 which is normally positioned within thewasherlike end 54 of the plunger 52, asillustrated in Figure 5. The rod55 is slotted at 51 and works over a key pin 58 to limit the slidingmovement of the rod 55. An adjustable yoke head 59 is secured to theouter end of the rod 55 and is adapted to be engaged by the pin- 60which is positioned on one end of an operating lever 6i, which controlsthe operation of the plunger 52 and the rod 55. The lever 6| is pivotedat 62 to the supporting bracket 63 which is mounted on the back of thewall 28 to hold the lever in operative position. The lever BI is adaptedto be operated by the rod 64 which slidably extends through the wall 28and which is formed with a yoke end 65 which pivotally and slidablyengages the pin 66 on the end of the lever 6|. However, the end of thelever 6| which carries the pin 66 is normally held by the spring catch61 in inoperative lockedposition, so that the lever 6| will notordinarily operate unless this spring catch 61 is first released. Thespring catch 61 is pivotally mounted at 68 and is formed with a shoe end69 which is adapted to be engaged by the rod when the rod Hi isoperated. The other end of the spring catch 61 is formed with a hook IIwhich engages the extreme end of the lever Bl.

The rod 10 is normally held in the position illustrated in Figure 5by-the coil spring 12 out of engagement with the end 69 of the catch 61.

Then when the cylinder B is compressed, the plate 41 will engage againstthe end of the rod Ill compressing the spring 12 and causing the catch61 to be lever B I One end of the rod 54 is slidably mounted in theplate 41 and an adjustable collar 13 causes the rod to be operated whenthe vacuum cylinder B is expanded, causing the yoke 85 to pull on thepin 56 and reset the lever 6| into locked'position held by the catch5']. A coil spring 'Mis secured to the end of the lever GI and acts toforce the plunger 52 with the rod 55 into the open end of the plunger 32when the catch 61 is released and the vacuum cylinder B'is compressedfar enough to release the collar from the plate 41, as illustrated inFigure '7, so as to permitthe lever 6! to push the plunger 52 inward.This permits my selector to operate to engage a slug such as 3'! with ahole-in it, as illustrated in Figure 8, perreleased from the end of theis actuated due to a hole in the slug, however,

mitting the pointed end of the rod 55 to engage through the hole of theslug to support the same on the rod and permit the washer end 54 toautomatically push the slug toward the working end 35 as the samerecedes back into the position illustrated in Figure 5, thusautomatically and virtually instantly kicking the slug over the dividingwall IS. The wall projects up from the bottom of the selector A andforms one side of ,the

slug ejecting chute Hi. The slug ejecting plunger 52 is pulled backquickly into its normal position by the rod 64 when the collar 13 isengaged by the backward movement oi. the plate ll in the expansion ofthe vacuum cylinder B. This operation causes the slug to drop into thechute l5, ejecting the same out of the selector A.

If a. slug such as 38 or 39 is inserted in the coin slot l4 and theselector is operated by pushing the handle l6 inward to compress thevacuum cylinder B,the working surface 35 of the plunger 32 will engagethe smooth portion of the slug, sealing the end of the plunger 32 on theslug, and

' as the cylinder B is released by the trip H and caused to be expandedby the spring 3|, the vacuum in the cylinder B and in the hollow plunger32 willbe sufficient to hold the slug long enough to carry it over thedivision wall 15 and drop it into the chute 16. Thus, the vacuum createdin the cylinder B is suflicient to carry a non-perforated slug over thedividing wall I5 and drop the slug into the ejecting chute. The workingsurface 35 is sharp-enough to fit the surface of the non-perforated slugand the vacuum built up in the cylinder operates to carrya slug of thischaracter into ejecting position. The ejecting mech-' anism includingthe plunger 52 and the rod 55 is inoperative when slugs of thischaracter without-a hole are ejected by the selector A, because thismechanism is not needed to assist in the ejection of the slug, owing tothe fact that the vacuum pulls the slug out of the coin slot fast enoughto keep it from falling straight down through the coin slot and'into'the chute H, which is directly below the end of the coin slot l4. Theejecting plunger 52 with its piercing rod 55 remains dormant even thoughthe catch 61 is released when operating against a closed slug or againsta coin such as 36, and before the plunger 52 has time to be operated bythe spring 14, the vacuum cylinder B has rei .irned to normal positionand the collar 13 has been engaged by the plate 47 to prevent the leverill from operating. A slight movement of the cylinder B is suificient tooperate the catch 61. When the rod 55 the lever 5| has been moved out oflatching position by the spring 14. This is important in the operationof this mechanism of my selector A because if this were not true theplunger 52 might push a coin over into the ejecting chute I6.

When a coin is dropped into the slot l4, it will be engaged by the gatearm 40 and. held in this selecting position until the lever I6 isoperated,

causing the working end 35 of the plunger 32 to 5 The fact that 6 engagethe surface of the same. the coin has an irregular surface like abuffalo. nickel, prevents the vacuum from being built up in the cylinderB to a sumcient extent to draw the coin over the division wall 15. Thus,after 7 the cylinder B is released, the coin 36 will drop straight downinto the coin chute 11 and out of the bottom or the selectorA intoposition to operate a coin controlled device or to ring the bell in atelephone box C. v

The selector units A may form a part of the coin box C of a tolltelephone, as illustrated in Figure 1'1, there being an individualselector for each denomination such as 5, etc., if it is desired. It isalso apparent even though it is not illustrated herein, that a separateselector plunger 82 may be provided for each denomination of coin in thetelephone box C with a single operating lever such as i8 and a singlevacuum cylinder B, which may be connected in a suitable manner tooperate singularly with the vacuum directed to the coin slot wherein thecoin is dropped. The slug ejecting chute 16 may be connected to the coinreturn chute 18 of the coin box C so that should an operator place aslug in any of the respective slots for the coins in the box C, and thelever I6 is operated to release the same into the coin box, the slugwill be immediately returned into the coin return chute 18.

The vacuum cylinder B is connected with an air check cylinder Dpositioned on one side of the same and supported on the wall 28, inwhich the plunger 18 operates through the rod 88 which connects with theplunger and the plate 41, so as to check or cushion the expandingmovement of the cylinder B.

My selector A may be made in the form illustrated in Figures 12 to 16respectively, wherein the coin. selectors E may be provided with diefaces 8| which are formed with virtually the identical die formation tofit the particular coin that is adapted to be used in the coin slot l4.The formation of the die faces 8| is more fully illustrated in Figure 18which shows the design of the die to be used in the selectors E wherethey are designed to select a buffalo nickel. The selectors E arenormally spaced apart as illustrated in Figure 12, on each side of thecoin slot |4. When the coin or buffalo nickel 38 is dropped into theslot l4, it is adapted to be stopped by the gate levers 82. The levers82 are pivoted at 83 and hold the coin in selecting position. If a slugis dropped into the slot |4, it will be held by the arms 82 in the samemanner. In this form-of the coin selector A, a hand or power operatingrod I8 is also employed which operates the tripping lever l1. The leverI1 is keyed to the shaft 28 which extends between the sides of thecasing, as illustrated in Figure 13. This shaft 28 operates to controlthe setting of the selectors E so as to bring them simultaneously intocontact with both sides of the coin 88 or a slug dropped into positionto be selected.

A yoke lever 88 is connected to the shaft 28 and extends virtuallyequally on either side thereof and is connected by the links 84 to thebrackets 85 which are positioned in staggered relation within the casingof the selector and rejecter A. The upper ends 88 of the brackets arethreaded to the sleeves 81 with a comparatively steep pitched thread, sothat the sleeves 81 may be rotated by the movement of the brackets 85after the brackets 85 have reached a predetermined point. The sleeves 81are rotatably mounted upon the hollow shafts 88, the inner end of theshafts 88 being closed at 88. The hollow shafts 88 are connected by thetubes 88 to the respective vacuum cylinders 8|, there being a separatevacuum cylinder 8| for each tube 88 and shaft 88.

The vacuum cylinders 8| are constructed as illustrated in Figure 14which shows a section through one of the cylinders, wherein an air checkvalve 82 is positioned in one end of the sliding cylinder portion 84 ofthe vacuum cylinder is carried by the lower end of the arms 88. Figure14 shows the cylinders 8| expanded and at the height of their vacuum,whereas Figure 12 shows one of the cylinders 8| telescoped with theportion 84 slid virtually over the sleeve 88. The staggered relation ofthe vacuum cylinders 8| is illustrated in Figure 15. Guide rods 8! guidethe cylinder portions 84 which form the lower ends of the brackets 88 onthe outside of the cylinders 8|, whereas a common guide rod 88 ispositioned between the same and a coil spring 81 carried on the rod 88acts to normally force the cylinders 8| into telescoped position, asillustrated in Figure 12. In moving into this position, the check valve82 exhausts the air from the cylinders.

The selector A in this form is provided with a slug chute 88 which ispositioned directly below the selecting position for the coin or slug,as illustrated in Figure 12, so that when the gate levers 82 are movedapart, if one of the selectors E has not removed the member or elementdropped into the position between the gates 82, it will drop directlyinto the slug ejecting chute 88. The slug ejecting chute projects out toone side of the selector A so as to discharge the slug out of theselector when it drops into the chute 88. I provide a coin receivingchute 88 which projects on either side of the top end of the slug chute88, but which extends out in the opposite direction and is adapted tocarry a coin dropped into the same, out on the opposite side of theselector A and to deposit the coin in any suitable receptacle or inposition to operate a coin controlled device.

Thus, when the selectors E are brought up into contact with the faces ofthe member dropped into the coin slot I4 and held in the positionillustrated in Figure 16, if the selectors E fit either face thereof,such as the buffalo of a nickel like the die design illustrated inFigure 18, the selector fitting the same should act to draw the coin toone side or the other of the slug chute 88. If neither of the selectorsE select the element from the selecting position, it is a slug and itwill be left to fall straight into the slug chute 88 and be thusejected.

The faces of the selectors E which are formed with a die to fit therespective coin to which the dies are adapted to engage, are formed witha series of perforations |88 to permit the vacuum set up in thecylinders 8| to operate through the connecting pipes 88 and the hollowshafts 88, to draw the coin properly fitting into the selector E byvacuum to one side of the chute 88, so that the coin may be dropped intothe coin chute 88 when the vacuum ceases. The be]. low shafts 88 areprovided with a hole |8l which is adapted to align with a slot I82formed along the inside of the sleeve 81, only when the selectors E arebrought together, as illustrated in Figure 14, fitting against eitherside of a coin or slug. Thus. a vacuum in the hollow shaft 88 becomeseffective through the openings III to engage the coin fitting in the dieface 8| and hold the same until the selector E moves back into theposition illustrated in Figure 12, whereupon the vacuum is broken or hassubsided to drop the coin 88 into the chute 88.

In operation, when the power lever I8 is operated to rotate the shaft28, the yoke 88 will draw the links 84 around the shaft 28 sufilcientlyto pull the brackets 88 toward each other, bringing the selectorsEagainst the respective sides of the coin 36. After the selectors Ehavecome in contactwith'the faces of the coin 36 and'the shaft 20 isfurther rotated, the threaded connection between the ends 86 and thethreaded Sleeves 81 will cause the sleeves 81 to begin to rotate, andthereby rotating the selector headsE and rotatingthe die faces BI on thecoin 36 in opposite directions. As soon as'either of these die faces fitthe coin, the coin will be rotated with the same, until the ends 86 ofthe brackets have moved towards each other the limit of travel in theoperation of the shaft 20. The threaded engagement between the ends 86and the threaded sleeve 81 is suiiicient to rotate the die faces BI ofthe selector heads E a complete rotation, thereby always insuring,fitting the face of the coin, no matter how the coin is dropped into theslot I4. Thus, as only one side of the coin may fit the. die faces at atime, one of the selector heads E will draw the'coin by vacuum to oneside the shaft 20 stops by the tripping lever !1 disarated by thetripping lever I'I.

engaging from the operating power lever I6, the" spring 91 then operatesto separate the selector heads E and causes the rotation of the sleevesB'I'and the heads E after they have moved back against the supportingbrackets I 03.

In the operation of the selector heads E, the gate arms 82 are releasedfrom holding the coin 36 or the slug, the moment that the selector headsE engage the same. It is also apparent that the heads E 'hold the coinor the slug between the same until the selector heads are sep- With thisconstruction of the selector A, where the die faces M are of a trueformation to'fit the coin, such as a buffalo nickel, a dime, atwenty-five cent piece, a fifty cent piece or a dollar, or any othersuitable coin, or member adapted to be used as a coin having aparticular die face, it is apparent that; only when the proper coin ormemher is used to fit the, die, is it possible to deposit the same intothe coin chute 99. If a slug like 31, 38, or 39, or any other similarslug which does not have the proper die face on one side thereof to fitthe die face BI, is endeavored to be used in this form of the selectorA, it will not be picked up by the vacuum in the selector heads E andthus, it will be dropped the moment that the selector heads separate,falling directly into the slug ejecting chute 98 which rejects the slugout of the selector A. 1 V

The gate levers 82 are operated on their pivot points 83 by the link I04which is pivoted at I05 so as to be rotated by being engaged by thepower rod I6 to rotate the link I04 inthe direction of the arrowillustrated in Figurelfi. When the link 104 is rotated in this manner,the connecting link I06 which connects with one of the gate arms 82,will be moved into open position, while the link I0'I will move in theopposite direction to the link I06 and through the connection of thelink I01 with the linki08, illustrated in Figure 13, the other gate arm82 will be moved into' open position. A suitable spring means holds thelink I04. normally in the position illustrated in Figure 16. As "thepower rod I6is pushed against the link I04, it will open the gate arms82 just prior to releasing the tripping lever I1. The mechanism operatesquickly when it is tripped and a selection or rejection is made of thecoin or slug which has" been deposited in the selector A.

The coin selector and slug ejector A in this last form is. positive inoperation and will operate to absolutely prevent the use of a slug inplace of a predetermined coin, where the die face 8| is made of the sameformation as the face of the coin. Thus, the efliciency of my selectorand slug rejecter will be readily apparent, wherein it is possible forme to provide a perfect coin selector and slug rejecter, therebyproviding a means of protecting coin operated devices with my selector,The facsimile die face of the predetermined coin to be selected is animportant feature of my invention and insures a perfect operation inselecting the coin, as well as a perfect operation in rejecting a slug.The only way that a slug could beat my selector would be to have thesame formed with die faces identical to the coin to be selected. It willalso be apparent that my selector is very efficient in its operation,owing tov the fact that no matter which way the coin is inserted in thecoin slot it, either one of the other selector heads E will pick it upand carry it into the coin chute 99, retaining the same to operate thecoin operated mechanism with which my selector is associated.

It is also apparent that the drawings are only illustrative to describea mechanism of the character set forth and to illustrate a means ofcarrying out the principles thereof, and it is obvious that the selectorcan be made just as small as desired and with the parts arranged'in anysuitable manner to carry out these principles of selecting a coin andrejecting any slug of any nature what'- soever, thereby preventing fraudin the use of slugs.
